QF Edition Rolex Cosmograph Daytona 116505 Everose Gold
A compelling execution of the precious metal Daytona, pairing robust 4130 clone architecture with a highly accurate Everose alloy plating tone.
Powered by Caliber 4130 Clone
The mechanical foundation of this timepiece is the highly regarded caliber 4130 clone. This movement mirrors the genuine architecture by utilizing a column wheel and vertical clutch system, ensuring immediate and judder-free activation of the chronograph seconds hand. It incorporates a paramagnetic blue Parachrom hairspring and KIF shock absorbers, providing notable stability against daily wear variables.
Regulated to an operational variance of 卤5��7 seconds per day prior to casing.
- �� Power Reserve: Approximately 36 hours
- �� Complications: Fully functional chronograph, running small seconds, 30-minute counter, 12-hour counter
- �� Winding Direction: Bidirectional via perpetual rotor

Features a sharp sunburst finish with deep rose gold-tone sub-dial rings. Crisp typography and evenly applied Chromalight indices.
Fixed tachymetric scale bezel with accurately engraved numerals. The metallic tone matches the mid-case plating seamlessly.

Why QF for This Reference?
Many collectors ask: ��Why not Clean Factory (CF) or BTF?��
While CF produces highly regarded ceramic bezels for steel models, QF is selected here for its specific formulation of Everose gold plating. It avoids the aggressive copper-red hue found in early BTF batches, presenting a softer, more authentic rose gold tone that aligns closer to genuine Rolex metallurgy under natural lighting.
Full Disclosure: Because this model relies on electroplating over a 904L steel base, it lacks the substantial weight of a genuine solid 18k gold Daytona, and the plating requires careful handling to prevent deep scratches from exposing the steel beneath.

Collector Q&A
Q: Does the chronograph function exactly like the genuine caliber 4130?
A: Yes, the QF 4130 clone movement features a fully operational column wheel and vertical clutch, allowing the chronograph seconds hand to sweep smoothly and the sub-dials to track elapsed minutes and hours accurately without stuttering.
Q: How does the Everose gold plating hold up to daily wear?
A: The factory uses a durable electroplating process over a 904L Oystersteel base. While resilient for standard use, it remains a surface treatment. Abrasive polishes or deep gouges will expose the stainless steel underneath, meaning it requires more careful handling than an unplated steel model.
Q: Is the dial color an exact match to the genuine 116505 black dial?
A: The primary black sunburst finish is highly accurate, and the sub-dial concentric circles reflect light correctly. However, under strict macro inspection, the rose gold metallic paint on the sub-dial tracks may show a slightly different grain structure compared to the solid gold appliques used by Rolex.
Q: What is the main drawback of this specific QF model compared to genuine?
A: The most significant tell is the physical weight. Genuine 116505 models are machined from solid 18k Everose gold, yielding a substantial and dense wrist presence. Because this replica is built on a lighter 904L steel base, it will feel noticeably lighter than the authentic piece when handled off the wrist.
